STOP AND WASTE DEVICE.

SPECIFICATION forming part of Letters Patent No. 495,575, dated April18, 1893.

' Application filed April 17, 1888- Serial No. 270,896- (No model.)

T0 aZZ whom it may concern..-

Be it known that I, HERMANN O. APEL, of Milwaukee, in the county ofMilwaukee, and in the State of lVisconsin, have invented certain new anduseful Improvements in Stop and WVaste Devices; and I do hereby declarethat the following is a full, clear, and exact description thereof.

My invention relates to stop and waste valve mechanism, and theinvention consists in certain peculiar and novel features ofconstruction and arrangement, as hereinafter described and pointed outin the appended claim.

In order that my invention may be fully understood, I will proceed todescribe it with reference to the accompanying drawings, in which-Figure 1 is a side elevation of my improved stop and waste valvemechanism. Fig. 2 is a transverse vertical section of the valve casing.

The objects of my invention are to produce a valve-mechanism which shallbe direct and positive in its action and which shall operate tosimultaneously shut and drain off water from the service pipes; andfurthermore to produce avalve-mechanism which shall, without anyabnormal change in its parts, either hold the water normally shutoff orlet on as desired. These results I attain by virtue of the constructionwhich I will now proceed to describe.

Referring to the drawings, A designates the inlet casing whichconstitutes the base of the valve and drainage casing, and which has, atone side, an inlet opening a the nipple b of which is externallyscrew-threaded to receive the street-connection B from the water-main.The upper part of this casingis formed with a wide internallyscrew-threaded opening to receive the externally screw-threaded lowerend of the vertical valve-casin g C. This valve-casingOis ofelongatedcylindrical form and is provided near its lower end with anexternal annular flange or shoulder a which rests upon a packing-ring f,the latter resting, in turn, upon the top of the inlet casing Acontiguous to its opening. In its lower part, adjacent to and just abovethe flange f, the casing 0 is provided with one or more drain openingsor ports (I, and the upper end of the casing is internallyscrew-threaded for a purpose to be presently explained. The lower end ofthis casing is closed, excepting asmall central portor opening 0, thepurpose of which will also be hereinafter explained.

D designates the drainage-casing which is also of oblong cylindricalform and of greater length than the valve-casing C so as to rise abovethe latter, as shown. The lower end of this drainage-casing rests uponthe top of the inlet casing A and is confined thereo'n by an annularupwardly extending flange 9 formed on the top of the casing A andabutting against the outer sides of said casing D.

Thus the lower end of the drainage-casing fits snugly between theflanges e, and g, and

the joint is packed by the ring f before described, so that no leakagecan occur. Near its lower end the casing Ais provided with adrain-opening or port 3 the nipple t of which is externallyscrew-threaded to receive a drai npipe (not shown) which may lead to asewer or to any other desired point. WVithin the internallyscrew-threaded upper end of the valve casing O is inserted theexternally screw-threaded lower end of a short cylindrical extension E,the upper end of which is externally screw-threaded to enter a socket inthe lower end of the cap I. This cap I is of cylindrical form and has anoutwardly enlarged base on the margin of which is formed a pendentannular flange m within which the upper end of the drainage-casing D isconfined. At one side the cap I is formed with an outlet opening 0; thenipple J of which is externally screw-threaded to receive agland u bywhich the service-pipe K is connected to the outlet opening 1;; apacking-ring acbeing interposed between the adjacent ends of the nippleand pipe, to form a tight joint. The top of the cap I is formed with anupwardly projecting extension L having a central vertical bore andexternally screw-threaded, as shown. Through the bore of this extensionL extends the valve-rod F; a gland B being screwed upon the upper end ofthe extension to compress a packing-ring S between it and the top of thegland, so as to form a tight joint around the valve-rod F. To the lowerend of this valve-rod L is secured the double-valve G, H. The upper ordrainage valve G is of hollow elliptical form and is composed of anupper halfsections m, h, and the adjacent edges of these rings areturned inwardly and confined between the upper end of the lowervalve-section and the external shoulder formed by the reduction of thelower endj of the upper section h. The lower valve II is conical in formand surrounds a stem q pendent from the lower end of the lower sectionof the upper valve G; a nut rbeing screwed upon the lower end of stem qto retain the valve II thereon.

Thus it will be seen that the upper valve G works wholly Within thevalve-chamber C while the lower Valve Hworks wholly within the chamber gof inlet-casing A.

From the description, thus far given, it will be seen that when thevalve stem is raised as shown in Fig. 2, the lower valve H is seated inthe opening a in the lower end of the drainage-valve chamber and thusthe water is cut off from the house-service pipe K. lVhen, however, thevalve-stem is lowered, the valve H is depressed out of its seat 0, therings n, 0, cover the drainage-ports (Z, and the Water flows freelyupward from inlet casing A, through drainage-valve casing C, and cap I,and into service-pipe K; thus supplying the water to the building asdesired. It the valve-stem be now raised, the valve II again seatsitself in the opening 0 cutting off the inlet chamber g. Simultaneouslythe rings n, 0, of the upper valve move upward off of the drainage-ports(Z and the water flows by gravity through the upper valve G, out throughthe drainage-ports d and thence through the outlet-port s.

It will be observed that the concentric space between the casings O, D,and E extends the full length of the former, and the purpose of thisarrangement is to produce a reservoir and air-chamber for the outtlowingwater, so that when the discharge from the drainageopenings cl exceedsthe emptying capacity of the outlet 8, the water shall rise in theconcentric chamber and thus permit the houseservice pipes to emptythemselves more rapidly than they could if the water had to flowdirectly through the openings d, 8. When these pipes have emptiedthemselves the compressed air in the upper part of this concentricchamber forces the remaining water entirely out of the chamber, thuswholly emptying the casings (J, D.

The above described movements of the Valve-stem are effected by thefollowing connections: M designates an L-shaped arm or standard theupper arm of which extends vertically and is bifurcated at its upperend; to receive a lever N; a hole Z being formed transversely througheach bifurcated member of the standard to receive a pin by which saidlever is pivotally connected to the standard. The upper end of thevalve-stem F is screw-threaded to receive a nut P which is formed with atransverse opening 0 in which the lever N works loosely. The lower endof the standard M loosely surrounds the extension L so that the standardmay swing freely about said extension L as a pivotal center withoutrequiring any abnormal change in the relative positions of the upperpart of the valve and drainage casings. The long arm of this lever N isconnected by a wire or other flexible connection U with a lever Tpivoted at Y and having its free end arranged to engage notches in asegment plate Z. This lever and its segment plate are assumed to beplaced against the wall of a room or apartment of a building. One ormore branch wires X may be connected, directly or indirectly to the wireU and are designed to connect with similar levers in differentapartments of the building. Ordinarily, the valve will be depressed, sothat in warm weather the water shall flow freely through the servicepipes and an adjustable weight V is mounted upon the arm N and issecured in any desired position of adjustment by a set screw IV. Thisarrangement is shown in dotted lines in Fig. 1. In winter the valve willbe normally held in raised position which is effected by the relativearrangement of parts indicated in dotted lines in Fig. lthat is to say,is swung around to the opposite side of the stem F from that shown insolid lines in said figure.

From the above description it will be seen that I have produced a simpleand compact valve mechanism, the parts of which can be readily assembledor separated, and which, without any abnormal change in the casing canbe adapted either to normally cut off, or let on the flow of water fromthe street main.

Having thus described my invention, what I claim as new therein, anddesire to secure by Letters Patent, is

In a stop and waste valve mechanism, the combination with a drainagevalve casing and an inlet casing located below the'drainage casing andcommunicating with the latter by a port, of an upper drainage valveformed of two skeleton semi-elliptical half sections and a conical plugstop valve pendent from the lower section of the drainage valve andworking within the inlet casing, substantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand, atMilwaukee, in the county of Milwaukee and State of Wisconsin, in thepresence of two witnesses.
